What does 'undersize' mean for these bearings?

Undersize bearings are manufactured to be slightly smaller than standard size. This set is 0.020 inches smaller, which is used when the crankshaft journals have been machined down to a smaller size during an engine rebuild.

Do these bearings come with new hardware?

This listing is for the crankshaft main bearing set only. Hardware such as main cap bolts or oil seals are typically sold separately and should be replaced during an engine rebuild.

How do I know if I need undersize bearings?

You need undersize bearings if your engine's crankshaft has been machined to a smaller diameter. Always measure your crankshaft journals and consult your service manual to determine the correct bearing size needed for your engine build.

Product Details

ACL has been making engine bearings for decades, and this crankshaft main bearing set for your Dodge Challenger is one of their staples. These bearings are crucial for keeping your engine's crankshaft spinning smoothly within the engine block. They sit between the crankshaft and the main bearing journals, reducing friction and wear. This specific set is designed for the 5.7L Hemi V8 engine found in many Chrysler products, including your Challenger, Charger, and Ram trucks.

This is a set of undersize bearings, meaning they are 0.020 inches smaller than standard. This is important if your crankshaft has been machined undersize during an engine rebuild to clean up wear or damage. Using the correct undersize bearing ensures proper oil clearance, which is critical for engine longevity and performance. ACL is known for well-built bearings, and this set is made to meet the demands of a performance V8 engine.

When rebuilding or repairing your engine, using the right size bearings is key. Make sure to verify your crankshaft's dimensions before ordering. If your crankshaft is standard size, you'll need a different bearing set. Always refer to your vehicle's service manual for detailed installation procedures and specifications.
